Source ports

This section may require cleanup to meet basic quality standards. The specific problem is: Consider adding supported major engine versions (Doom/DoomII, Heretic, Hexen, Strife) and supported limit-removing mod/map types (Vanilla, Boom, MBF, ZDoom, GZDoom, MBF21, etc.) for each engine. You can help by modifying the article. The discussion page may contain useful suggestions.

A more exhaustive list is available on Wikipedia and a set of comparison tables is available on DoomWiki.org.

Latest Git builds of ZDoom, GZDoom, UZDoom, LZDoom, and Odamex are available at DRD Team Development Builds.

• Doom Legacy
• ZDoom
  • GZDoom
  • UZDoom

Name	Description
ZDoom	Renderers available: Software. Limit-removing source port that has features such as high resolutions and all-new editing features for modders. No longer maintained by the original developer.
GZDoom	Renderers available: Vulkan (Default), OpenGL, OpenGL ES, Software - SoftPoly. Based on the same code as ZDoom, except it also uses an OpenGL and Vulkan renderer. Nearly every mod should work with GZDoom, specifically ones that use special effects. A widescreen frontend pack created by Nash Muhandes is also included for v4.5.0 and onward. Highly vanilla unfriendly.
UZDoom	Renderers available: Vulkan (Default), OpenGL, OpenGL ES. Fork of GZDoom made after GZDoom received commits with untested LLM-generated code. Nearly every mod made with GZDoom should work with UZDoom. Highly vanilla unfriendly.
LZDoom	Renderers available: Software (Default - DirectDraw via D3D9 legacy), OpenGL. A version of GZDoom designed for low end computers that supports older hardware and older software rendering. Defaults to Software rendering. It's fast software rendering mode is powered by D3D9s DirectDaw legacy compatibility mode. OpenGL - Hardware Accelerated renderer included. Replacement for QZDoom. Highly vanilla unfriendly.
Doomsday Engine	Renderers available: Software, OpenGL. Easy mod and addon management with enhanced graphics and effects.
Zandronum	Renderers available: Software, OpenGL. Based off modified ZDoom code. Use this source port to play online, as it significantly overhauls the netcode from ZDoom. Highly vanilla unfriendly.
Odamex	Renderers available: Software. Source port based on ZDoom 1.22 (and parts of 1.23) that focuses on multiplayer while staying close to the original Doom.
PrBoom	Renderers available: Software, OpenGL. Limit-removing source port based off Boom that aims to preserve the feel of vanilla Doom while adding modern editing features. Includes an OpenGL renderer and supports high resolutions. Development ceased in 2008; consider using PrBoom+ instead.
PrBoom+	Renderers available: Software, OpenGL. Based off PrBoom. Extends the port with more features.
DSDA-Doom	Renderers available: Software, OpenGL. Fork of PrBoom+ which adds support for Heretic, Hexen, MBF21, and Doom-in-Hexen, as well as several quality of life improvements.
PrBoom: Ray Traced	Renderers available: Vulkan. A fork of PrBoom+ that implements ray tracing graphics. Includes an optional DLSS plug-in. Requires a GPU capable of using Vulkan with ray-tracing extensions.
Chocolate Doom	Renderers available: Software. A source port that aims to accurately reproduce the experience of playing vanilla Doom. Renders at a low-resolution (that's upscaled to higher resolutions) and purposefully keeps the original game's limits. Strictly vanilla faithful; consider using Crispy Doom for QoL and mod compatibility enhancements.
Crispy Doom	Renderers available: Software. A limit-rising and double-resolution off-shoot of Chocolate Doom with visual and gameplay enhancements while remaining compatible with vanilla and Chocolate Doom features. Highly vanilla faithful, but more mod-compatible than Chocolate Doom.
Woof!	Renderers available: Software (with acceleration). A modern continuation of WinMBF, a Boom-derived source port, with quality-of-life enhancements and support for new modding features.
Nugget Doom	Renderers available: Software (with acceleration), Direct3D, OpenGL A fork of Woof! with additional features including an extended FOV range, rewinding similarly to DSDA-Doom, optional mini-map, and a customizable Nugget HUD.
Doom Retro	Renderers available: Software (with acceleration), Direct3D9 (Default), OpenGL. Source port based off Chocolate Doom that supports vanilla, limit-removing and Boom-compatible maps and makes a few other changes/fixes for the modern age while still keeping the classic Doom experience.
Competition Doom	Renderers available: Software. Source port based off Chocolate Doom used for speedrunning.

Launchers
